Phenolic Resin with Fabric Wear Ring

Model NO.: GST Application: Cylinder Performance: High Pressure Standard: Standard, Nonstandard Shape (for Gasket): Ring Gasket Brand: Def Delivery: 5-7 Specification: ISO, SGS, TUV HS Code: 848410000 Material: Phenolic with Fabric Type: Stationary Seal Shape: O-Ring Style: Floating Seal Function: Guide Sealing OEM: Accept Trademark: DEF Origin: China GST is the DEF Seal Solutions proprietary design of hydraulic Wear Ring or Guide Ring. The function of a hydraulic wear ring is to guide the shaft and hole sealing of a hydraulic cylinder, absorbing transverse forces. At the same time, it previents metal-to-metal contact, optimizing the performance of the sealing system. 
1. Good dimensional stability, can absorb stock
2. Uniform distribution of the large radial force
3. Low coefficient of friction, good sliding performance
4. Higher load bearing capacity
5. Excellent wear resistance
6. Wipe effect
7. Easy to install
8. Long service life

-Material
Phenolic Resin with Fabric Reinforcement (HG)
-Type of cut
The Angle Cut is the most frequently used standard type of cut. Rings with other types of cut, like Straight Cut and Step Cut are available on request. 
-Design Type
DEF guide rings(GST) has a rectangular cross-section with rounded or chamfered edges, thus preventing impermissible edge force in the corner radius of the grooves. The chamfers also serve to facilitate installation, e. G. When inserting into the cylindrical tube or guide bush. 
The ring ends are finished as standard with an angle cut. 
Strip material is available in rolls or precut to size to fit with the gap necessaryPlease feel free to contact us if you need more details about our factory and products.
